How often have you wished that OS-Tooltips would provide more functionalities like MultiLine-Text, Background-Color, Embedded Images, … . The time you faced those problems is over since today where JFace ToolTips are available to the public.

Easy isn’t it but there are many many more things available to you. You can add any control you want to the tooltip by subclassing org.eclipse.jface.window.ToolTip and providing your own implementation for createToolTipContentArea.
